Ana Ivanovic and Eugenie Bouchard were given a pleasant surprise this afternoon when they were told that their second-round Wimbledon match was being moved from Court 12 to Centre Court because of Victoria Azarenka's withdrawal.
Twelfth seed Ivanovic was the favourite but it was Canadian teenager Bouchard who upset the odds to progress.
Read how it all unfolded in our game-by-game updates below.
Righty ho, after Azarenka's last-minute withdrawal it's now Ana Ivanovic on Centre Court against Eugenie Bouchard. Warm-ups have just finished and the players are ready to start. Canadian teenager Bouchard to serve first.

Bouchard reels off three points in a row in rapid fashion and what a start this has been for the 19-year-old.
WHO? Some of you may be wondering who young Miss Bouchard is. She is a Canadian 19-year-old playing in her first senior Wimbledon. She knows her way around the grass here though as she won the junior title 12 months ago. She is currently ranked at a career-high 66 in the world and is Canada's top woman.
The sun breaks through the clouds at Wimbledon. We're expected to have a third dry day in a row at SW19. Yippee!
Better from Ivanovic as she holds to love to get on the board.
This is really impressive from Bouchard. She's not faltering at all at the moment despite her huge lack of experience compared to her opponent.
Ivanovic looks up to her box for support after a tame drop shot doesn't make it over the net. She has to pick it up here.

Bouchard must be wondering if it's always this easy against a top seed on Centre Court at Wimbledon! Another comfortable hold to 15 for the Canadian who hasn't offered a single break point since the opening game of the match.
At 40-0 it looks as if Ivanovic will hold easily but Bouchard prolongs the game a little longer with a firm low pass that the Serb can't loop over the net.
The 12th seed does hold on the next point though, kneeling low to push a forehand up the line that Bouchard can then only drag wide with her backhand.

Just as I say that, Bouchard double faults twice in a row when 40-15 up. Now deuce.

No, is the answer to that as Bouchard bashes a forehand up the line that Ivanovic can't return.
DOUBLE BREAK! Deary me, what a limp performance this is from Ivanovic. She's broken again and now Bouchard will serve for the match and a place in round three of Wimbledon.
You might expect Ivanovic to give up but she now has two points to get back one of the breaks.
ONE BREAK BACK! The first is wasted as Ivanovic hits long but she converts the second in style, tracking down Bouchard's surprise drop shot and then finding the line with a backhand.
Double fault from Ivanovic at 15-30 and Bouchard has TWO MATCH POINTS.
GAME, SET AND MATCH!
Bouchard wildly lashes a backhand wide on the first attempt but then Ivanovic finds the net to give Bouchard the win.
A first-ever appearance on Centre Court for the 19-year-old and didn't she do well. This match was supposed to be on Court 12 but got moved to Centre because of Azarenka's withdrawal.
After the match she tells BBC Sport that she loves it at Wimbledon, describing it as her "second home".
Next up on Centre is exciting Frenchman Jo-Wilfried Tsonga. Stick around on Sports Mole for coverage of that one going live very soon.
